To all whom it may concern.-

Be it known that I, FnANK J. Rossum., a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Sign-Receptacle Fastenings, of which the following is a specification.

Thls invention relates to the subject of electrical fixtures, and more particularly to the mounting of electrical receptacles and analogous bodies on a sign board, junction box cover, or other supporting element.

To this end the invention has in view a. simple, thoroughly practical, and inexpensive form of fastening device ca able of general application to any and all 'nds of sign receptacles and analogous electrical bodies without requiring any material alteration or change in the construction of the latter, while at the same time providing means for readily and satisfactorily fastening the receptacle or other body to the sign board or supporting element in which it may be installed. l'n this connection, the invention has particularly in view the provision of n form of fastening device designed to be carried with and by the supporting elenient and admitting of the quick and ready insertion ofthe receptacle or other body into the receiving hole designed therefor, and at the same time eii'ecting the fastening of the receptacle or other body in place.

A more general object of the invention is to provide a receptacle or equivalent mountd ing which admits of the receptacle being mounted and secured' in smaller and more confined places than is usually possible with the ordinary construction. Also, the invention provid effective means for fastening or clamping the whole body of the receptacle, and at the same time forms an electrical holding means which prevents breakage of the porcelain. Furthermore, the improved mounting is of such a. nature as to require no skill for the installation thereof.

W'it-h these and many other objects in view, which will readily appear to those familiar with the art as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated, and claimed.

The improved fastening device, which provides for the mounting of the electrical receptacle or analogous body, may be utilized 1n different forms, and various modifications may be resorted to in the applica tion of the invention, but certain practical embodiments of the latter are shown in the accompanying drawings, in which:

Figure l is a side elevation illustrating an electrical receptacle fastened upon a sign board or other supporting element by the improved fastening device claimed herein. Fig. 2 is n. sectional elevation of the application of the invention shown in Fig. 1. Fig. 3 is an elevation of a sign board or supporting sheet equipped with a fastening eyelet such as contemplated by the present inrentilpn. f

Li e re erences designate oorrespondi parts in the several figures of the drawingangr For illustrative purposes, the invention is shown in the drawings as applied in connection lwith a sign receptacle of the kind embodying in its organization a one-piece porcelain or equivalent receptacle body designated in its entirety by the numeral 1. This body is illustrated as provided at what may be termed its outer end with an annular bindin collar 2, presenting at its inner side a. binding shoulder which impinges against the sign sheet or other supporting element S in opposition to the action of the fastening device orming the subject matter of this application.

The fastening device, as an entirety, may be properly termed a fastening eyelet, inasmuch as the same is carried by the supporting element and surrounds the receiving hole 3 therein, said eyelet also projecting beyond one side of the supporting element so as to entirely surround and clamp the receptacle body which is inserted therethrough from the outside.

Referring particularly to the embodiment ofthe inventlon suggested in Fi s. 1, 2, and 3 of the drawings, the numeral desi ates the fastening eyelet, which is illustrated as consisting of a. sheet metal collar or band bent into circular form corresponding to the circular shape of the receiving hole in the supporting sheet and secured to the latter by any suitable means, So that in effect the fastening eyelet will be a part of the supporting element, thus only requiring the rece tacle or analogous body beinv inserted t rough the receiving hole and the said eyelet to `provide for installin and fastening the sai body in place.

le varions expediente may bo resorted to to brovnlc for the connection bet-woon the fusto-mn 'f oyelet. and supporting element, n profi-.ruhe and )rncticul construction is shown in Figs. I, a und 2l, and this eonsn'nctimi involves ilu.- feature of providing the cyclet at what may be termed its outer edge, with an annular retaining seat 5 receiving the edge portion'of the receiving hole 3, and with iin'exterior outturned retaining flange 6 engaging over the outer ed e poition of the. hole 3 in the supporting e ement, thus securing the fastening eyelet against longitudinal displacement, while rota-ry movement or displacement thereof may be prevented by any suitable means such as providing the supporting ele ment upon one side thereof with a stop lug or equivalent lproject-ion 7 engaging b etween the ends of tie collar or band constituting the fastening eyelet. In this connection, it will be observed that the collar .or band forming the eyelet is of the split ring type, and inasmuch as sheet metal is preferably utilized in making e elet, the same acts as a spring clamp to yie dingly clamp upon the whole body of the receptacle or other electrical fitting.

In order to positively lock the rece tacle or other body 1 agxainst longitudine displacement after aving been inserted through the eyelet 4, the said body may be conveniently rovided with an external an nular catch oulder 8 behind which snaps the inner locking edge of the eyelet, and mid l v edge portion of the eyelet may be provi ed with a. .continuous series of corrugations 9 forming locking elements adapted to interlock with corresponding and complemental elements 10 arranged in an am nular series upon e body l adjacent to the shoulder 8. These interlocking elements 9 and 10 serve to prevent rotary movement or displacement o the receptacle or other body L In the applied position of parts shown in Figs. 1 and 2, the front shoulder or {iange 2 of the receptacle or other body overlies and covers the flanged outer edge portion of the eyelet 1t.

From the foregoing it will be observed that a distinctive feature of the present invention is that the body of the receptacle is cylindrical and free from projections, and that the fastening device or eyelet engages a part of the receptacle smaller than the genera-l diameter of the receptacle body. This admits of employing the invention in connection with a plain round hole in the supporting element, and also involves au operation wherein the receptacle and the fastening device are simply pushed together and throu h the hole without rotary movement at a Furthermore, it will be observed that the fastening device or eyelet is a. complete device in one piece.

Uthmmmlilcatious will readily sngfost tluenisvlvvs to those skiiled in the nrt, nm it will he. nnilorstmul that vin-ions changes in the form, iroportion, and minor details of construction muy lm resorted to without dcparting from the spirit or sncrilicing any of the advantages of the invention.

I claim:

In a mounting for electrical receptacles and analogous bodies, the combination with the supporting element and the receptacle body, of a one piece fastening eyelet consisting of a sheet metal collar having one edge portion engaging in the hole of the supporting elementand its opposite edge portion engaging with the rece tacle body.

2. In a evce of the class ascribed, the combination with the supporting element having a receivin hole, and the receptacle body, of a astenlng eyelet consisting of a spring split collar or band having one edge portion interlocked with the supporting element within the receivin hole, and its o posite edge portion provided with a lociiig element engaging the receptacle body.
